200 This requires sleeping, which can't be done from inside IRQ handlers.

381 GPIO numbers are unsigned integers; so are IRQ numbers.  These make up
382 two logically distinct namespaces (GPIO 0 need not use IRQ 0).  You can

395 to use an IRQ number that didn't originally come from gpio_to_irq().
401 or free_irq().  They will often be stored into IRQ resources for platform
402 devices, by the board-specific initialization code.  Note that IRQ trigger
403 options are part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are
408 when the IRQ is edge-triggered.  Note that some platforms don't support
